DESCRIPTION JP2001061197
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to
experiencing a sound field such as surround sound and realism with headphones.
[0002]
2. Description of the Related Art Conventional headphones have only one driver on the left and
right, and can reproduce sound field by stereo reproduction, but can not reproduce sound field
with realism such as surround sound.
[0003]
Although sound field reproduction with a sense of reality is realized by a surround system that
produces sound from speakers, it requires a plurality of speakers, amplifiers, etc., resulting in an
increase in cost and a need for a large storage space. It was dead.
[0004]
The only information that headphones can output is sound.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for
realizing realistic sound field reproduction at a low cost even in a narrow place.

SUMMARY OF THE INVENTION The present invention is characterized in that a realistic sound
field reproduction is realized by headphones.
[0007]
In the above headphones, for example, an arbitrary number of drivers are disposed at arbitrary
positions on the upper and lower sides of the ear on the left and right respectively.
[0008]
The above headphones may be disposed with an arbitrary number of vibration generating means
such as an eccentric motor or a solenoid at any place.
[0009]
The above headphones may have any number of bass drivers arranged.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION The headphones according to the present
invention are provided with drivers for upper, lower, front, rear, etc. for each of the left and right
ears, for example. The sound heard from the lower driver, the sound heard from the front and the
sound heard from the rear are output from the driver and the rear driver, respectively.
[0011]
For example, in the above configuration, the front left, back left, top left, bottom left, bottom
right, front right, top right, bottom right drivers are front left, back left, top left, bottom left, right
front, right back, top right, and so on. The signals of the lower right eight channels are input, and
the sound is reproduced by each driver outputting a sound.
[0012]
The headphones of the present invention can also be provided with a vibration generating device
such as an eccentric motor or a solenoid at an arbitrary place to produce a sense of presence by
vibration.

The headphones according to the present invention can also be arranged with a driver dedicated
to bass to produce a sense of presence by bass reproduction.
[0014]
A great sense of reality can be obtained by combining the effects of sound field reproduction
with vibration and bass reproduction by a plurality of drivers.
In addition, the effect can be expected even if only one of sound field reproduction, vibration and
bass reproduction by a plurality of drivers is used.
[0015]
Also, the headphones according to the present invention are configured by three drivers for the
left and right ears, upper front, upper rear, lower center, upper front, upper back, lower front,
lower. It may be configured by four drivers for later use.
The important thing is that the sound field reproduction which spreads up and down, left and
right and back is done by a plurality of drivers.
[0016]
With the headphones according to the present invention, headphones provided with front output
and rear output respectively on the left and right can be used for surround reproduction of
various music and movies.
[0017]
Effect of the Invention Since the sound field can be reproduced in the upper, lower, left, and right
directions, when used in a game machine or the like, an effect with a sense of reality can be
achieved.

The conventional surround system requires a plurality of speakers, requires a place having a
certain size, or requires an amplifier for driving the speakers as many as the number of speakers,
which increases the cost. Compared to speakers, no current flows, so there is no need for a large
current amplifier, and the device can be made smaller and cheaper.
[0018]
By generating vibration, it is possible to produce an effect that further enhances the sense of
realism.
[0019]
An effect of further enhancing the sense of presence is possible by the bass driver of the bass
driver.
[0020]
The headphones themselves are also cheaper than the speakers.
Also, I do not need to take a place.
